It's almost time for Gina's class to take their midterm, and has she got a test ready for them! They're going to the Hades Cradle, an industrial fortress from the Age of Wonders. . . located in Atlas's armpit! Hazmat suits and Febreeze will only protect them so much; they've got to be totally on their best game to succeed and pass the test safely. But when they decide to make a pre-test trip to the spot, Gina has to race against time before they come up smelling like. . . well, not roses!
